Brilliant² Rota Pol
The Lindsey Optics Brilliant² Rota Pol is designed to fit 4×5.65” matte boxes used in cinematography. It allows simple and effective rotation of the included 138mm Round Brilliant-Pol Circular Polarizer. A Rota-Pol polarizing filter is sometimes called a RotaPola . . . it’s the same type of product.
Large Diameter Clear Aperture
The included large 138mm diameter polarizer gives a large 5.1″ clear aperture, useful even with wide angle lenses and large zoom lenses.
Quick and Sure No-Slip Rotation
Rotation of the polarizer can be done by spinning either of the two thumb wheel gears by hand or with a motor mounted on the 1/4–20 thread in the handle.
Our superior mechanical design includes an aluminum main gear in which the138mm Brilliant Pol Circular Polarizer filter is mounted. That main gear rests on internal Delrin™ rollers for smooth no-slip rotation, The main gear is driven by aluminum thumb wheels that are geared with standard 0.8 pitch gear teeth for use with motorized wireless remote systems.
Now you can have a rotating polarizer in your matte box, even if your matte box does not have a rotating filter stage. In matte boxes with a rotating stage, our Rota-Pol is quick to insert and once installed, it’s fast and easy to adjust, It does not cause any interference with rods in a rod mounted matte box.
Circular Polarization – Prevents Accidental Cross Polarization
Our Rotapola is delivered with a mounted Brilliant Pol 138mm Circular Polarizer which has 38% transmission, resulting in a 1.5 stop light reduction.
As with all circular polarizers, the Brilliant Pol Circular Polarizers are constructed with two internal components, a linear polarizer that will reduce reflections when rotated and a “quarter wave plate” that spins the light entering the camera lens, preventing any cross polarization inside the camera and lens system.
Water White Optical Glass with MC Coating
Lindsey Optics Brilliant-Pol Polarizing Filters are constructed using Schott B270 “water white” optical glass and have a broadband multi-layer anti-reflection coating which dramatically reduces flare, stray light and ghost images caused by filter to filter reflection. Contrast and color saturation are increased. They are ground and polished to be very flat and will not cause distortions or focus shifts, even with long focal length lenses.
An Essential Filter for Enhancing Every Scene
Brilliant-Pol Polarizers are extremely efficient at reducing reflections on glass, water and other reflective objects. They also saturate blue skies and increase color saturation in landscapes by reducing micro-reflections in the scene.
The Brilliant² Rota Pol rotating polarizer works with Arri™, Bright Tangerine™, Chrosziel™ and Vocas™ and other professional matte boxes. It does not work with RedRock Micro™ matte boxes.
